Read each question carefully and use the Converse of Pythagoras Theorem to determine if the given triangles are right-angled triangles.
1. Which set of side lengths forms a right-angled triangle?
3, 4, 6
5, 12, 13
7, 8, 9
2, 3, 4
2. The sides of a triangle are 8 cm, 15 cm, and 17 cm. Is this a right-angled triangle? Show your work.
3. A triangle with sides measuring 6 inches, 8 inches, and 10 inches is a right-angled triangle.
True
False
4. According to the Converse of Pythagoras Theorem, if the square of the longest side of a triangle is equal to the sum of the squares of the other two sides, then the triangle is a triangle.
5. A carpenter is building a frame for a window. The sides of the frame measure 90 cm, 120 cm, and 150 cm. Is the frame perfectly rectangular (i.e., does it have right angles)? Explain your reasoning.
